Quick Answers

So, is Core i7-4785T better than Core i5-7400?

Yes. Core i7-4785T is the better all-around CPU here. It gives you a 17.7% average FPS lead across 50 shared CPU game tests in our data and 0.2% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i7-4785T is the better pick. According to our tests, it delivers 17.7% more average FPS across 50 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Core i7-4785T is the stronger fit. You are getting 0.2% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

Which one is the smarter buy today, not just the cheaper CPU?

Core i7-4785T is still the much better call for a fresh build. Core i7-4785T comes in 4.1% more expensive on MSRP at $306 MSRP versus $294 MSRP, and it still gives you a 17.7% average FPS lead across 50 shared CPU game tests in our data. Core i5-7400 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2017 platform. Even with 3.9% better value on paper (18.6 vs 17.9 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1151.

Which one is more future-proof for 2026 and beyond?

Core i5-7400 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2013). That makes it the safer long-term bet.
